Mitochondria fuse together to share contents and mitigate stress
Mitochondria undergo continuous fusion and fission processes, with fusion serving as a critical mechanism to mix organellar contents, rescue damaged components, and mitigate metabolic or environmental stress.
The retrieved literature robustly supports the claim that mitochondria fuse together to share contents and mitigate stress. Multiple foundational reviews and mechanistic studies (e.g., Papers 0, 1, 3, 6) explicitly describe mitochondrial fusion as a quality-control mechanism that allows damaged mitochondria to undergo complementation, mixing their contents to restore function and alleviate cellular stress. There are no papers contradicting this well-established biological function.

Paper 0 explicitly notes that mitochondrial fusion mixes the contents of partially damaged mitochondria to mitigate stress as a form of complementation.
